Features Precision Thread Repair: Easily fit the socket set into the screw hole of metal workpieces to create high-accuracy standard female threads, ensuring secure fastening and stability. Reliable Maintenance Tool: In case of thread processing errors or damaged female thread holes, the wire thread insert efficiently restores and strengthens the threads, prolonging the lifespan of the workpiece. Enhanced Connection Strength: The thread socket, designed with elasticity, enhances the connection and fatigue strength of the thread, ensuring long-term durability and reliability. -Resistant Material: Crafted from stainless steel for excellent resistance, ensuring durability and longevity, making it ideal for repairing threaded holes. Metric to Imperial Conversion: The wire thread insert allows for convenient and fast conversion between metric and imperial threaded holes, providing versatile compatibility for various applications. Specification: Item Type: Wire Thread Insert Material: SUS304 Model: M12 x 1 Thread Specification: M12 x 1 Outside Diameter Before Installation: Approx. 14.3-14.8mm / 0.56-0.58in Drill Bit Diameter: Approx. 12.m / 0.5in 1D Length After Installation: Approx. 12mm / 0.5in 1.5D Length After Installation: Approx. 18mm / 0.7in 2D Length After Installation: Approx. 24mm / 0.9in 2.5D Length After Installation: Approx. 30mm / 1.2in 3D Length After Installation: Approx. 36mm / 1.4in Wire Thread Insert Model Description: For Example: M3 x 0.5 x 1.5D, which means that after the screw set is completed, the female thread is M3, the pitch is 0.5, and the length is 1.5D (length is 1.5 times the diameter, that is, 1.5 x 3=4.5mm ), the length here refers to the length after installation. Wire thread inserts are also called threaded sheaths, stainless steel threaded sleeves, wire sleeves, and braces. They are a new type of internal threaded fasteners made of high-strength, high-accuracy diamond-shaped cross-section steel wires; Application to low-strength engineering materials such as aluminum alloy, zinc alloy, copper, plastic, etc., can significantly improve thread strength and wear resistance.
